Two questions for you:
1-) What kind of glue did you use with the hull skins? It doesn't wrinkle...
2-) What exactly is this foam? Can you give me a comercial name or brand?

Best regards

For hull skins I used Budapren glue. It is kind of like contact cement glue. Smelly though, but great for big surfaces and long pieces, and it is not water based so paper doesn't absorb it.
Foam I used is is Great Stuff big gap filler. For my opinion it is a little to soft but still worked not bad. I also used a thin layer of plaster to make it smooth.

Bottom section of the hull is complete,although I am disappointed with the kit. While fit of the parts is great ,colors aren't :( there 3 different shadows of the colors. Lighter at the front ,darker in the middle and lighter at the end of the hull.... I am thinking to even this out a bit and spray it with the paint to make it even color along the hull. What are you thoughts folks????
